Volume Pedal Pots?

Buck Reid · Post by **Buck Reid** » 24 May 2003 6:54 pm

I know this has been discussed here before.....but can anyone help me find potentiometers for my Emmons volume pedal? I don't like the 'Claristats'. Can we still get Allen Bradley's or something of equal quality? Thanks in advance!!

A/B went out of business...... Some years ago.

The chances of findimg orginal A/B pots is about like winning the lottery.

There was mention in the past of a pot being sold by Paul Franklin Sr. Anybody know what it is and if he's still selling it?

I had Paul Sr put a couple new pots in my Franklin (stereo) pedal. One is a Clarostat and the other says "PEC type K made in Canada" on it.

I think the PEC pots should have
a part # KAR64. Those are the audio
taper 500K pots. Supposedly they
don't last quite as long as the
Clarostats but they might sound better
& they're cheaper anyhow. Steer
clear of the Ohmite CA-5041's.
They're now only linear taper &
(as Jay Dee can tell you) sometimes
they're scratchy right out of the package.
Some Clarostats are as well.

any body try the one's that Emmons sell's?

I found that I own one (1) AB Vol. Pot, but, I won't part with it! So, why don't I just keep my mouth shut? Because I need a good foot-locker! “Uh~” “Flakey Jakey” wknsg®

Buck, Do a search in electronics Feb 21 of this year. You will see that some A-B pots are also made in Mexico and they're not worth a flip. Same as a Claristat made in Mexico. Big John on tha A-B pot if it's made in USA I'll wrestle you for it. [This message was edited by Kenny Foy on 28 May 2003 at 06:05 PM.]

I've got 2 NIB Allen Bradley pots 1 500k and 1 1000k like Goodrich uses in the L10k pedal
Has anyboby tried that new CD2-A potless pedal from Goodrich?

Kenny; Yes, my A/B pot is U.S.A., but; I've had a backache lately! Sorry! "John"

Buck, the old standard Ohmite CA5041 is still available . . . just put one in an Emmons pedal of mine. Should be available from Newark Electronics, Allied Electronics, and other large suppliers of components. The old ShoBud skates used the Ohmite pots, before AB made them for the military. The pots steel players use is a Hot Molded Carbon pot, that is a MIl SPEC pot. Since the military went solid state, even they don't use too many 2 watt pots anymore.
I've sent Seymour an Ohmite pot to evaluate. Chick Donner

Thanks Chick!

Those new CA 5041's are LINEAR taper.
They ain't like the old originals.
Read my previous post up above.

John Lacey · Post by **John Lacey** » 2 Jun 2003 5:03 am

Well it took 3 Clarostats before I finally ran into one that didn't scratch or whoosh. Hope it lasts.

Jay Ganz · Post by **Jay Ganz** » 2 Jun 2003 6:47 am

John,
Didn't you try one of those PEC pots
from up your way. Did they have any
with audio taper?

John Lacey · Post by **John Lacey** » 3 Jun 2003 7:12 am

No, they're linear, Jay. They are clear and clean and cheap, it would just be a matter of adapting to that taper. A fairly tall order.

Chick Donner · Post by **Chick Donner** » 10 Jun 2003 10:00 am

I've got to differ with Jay Ganz above; the Ohmite CA5041 pots are NOT linear, but are still an audio taper, just like always. Just put one into one of my Emmons pedals . . . works fine. Just ordered several more from 'onlinecomponents.com' in Los Angeles.

I've been reading these threads about pots with interest. Surely someone must still make a decent pot. Next time I need one I'll probably try the Ohmite. The CA5041 is definitely log taper (as opposed to the CU5041 which is linear). Here's the data sheet if anyone is interested:
http://www.ohmite.com/catalog/pdf/potentiometers_molded.pdf

I noticed that there is no spec for rated life (# of rotations).

Seems like there was a thread a while back where someone found a couple of promising pots that have conductive plastic elements. Did anyone ever try any of those?

Jay Ganz · Post by **Jay Ganz** » 11 Jun 2003 6:32 am

I've tried at least a half dozen of the
new CA 5041's & they come on so quick
at the begginning, they sure seem like
a linear taper. Half of them were
scratchy right out of the package as well.

I've not yet had a bad Ohmite pot. It's true that the "zero" point is a little trickier with the Ohmite than the AB, but so what?

Bruce Derr, I THOUGHT I read a "life cycle" of one million operations lock to lock, though that MIGHT have been on the Clarostat datasheet. I know I saw it on one of them. It would be the same, since both pots are Mil Spec.

When ya need a pot,any pot will do,

Gino Iorfida · Post by **Gino Iorfida** » 11 Jun 2003 9:37 am

well, there are 3 ways to deal with a linear taper pot--
1) learn to deal with the aweful taper
2) get a larger value pot and slap a resistor across it, making it more logaritymic or
3) dig up the old Goodrich patent for a cam style pulley, being slightly elliptical and off center-- maake any pot logarythmic (probably why goodrich designed it in the first place, the declining availability of good audio taper pots)

However, there are still a LOT of NOS/surplus good quality audio taper pots out there plus a lot of good ones made for standard guitar volume pedals, however, they may not be 500k pots. Not a big deal, if you dont mind putting a matchbox or other buffering type device before the pedal. THAT may be our solution after all... and another 20 years downt he road when that doesn't work anymore, there is always the Goodrich and Hilton type potless pedals

At the risk of opening a can of worms (as I did in the distant past), I have and do use a 500K linear taper pot. in my volume pedals. I started using them because they were/are significantly cheaper than the logrithmic taper pots. As for their playability, unless you have a tendency toward heavily "swelling" the pedal, they function very similarly to the sought-after pots. The fact of the matter is, with the first one I bought I didn't realize it was a different type of taper. It just seemed to provide a much more accurate control over the volume swell. It neccessitated more careful right-foot action which I adapted to without giving it a thought.

I have two Goodrich 120 pedals. One with the linear taper and one with the logrithmic taper. The linear taper has been my first choice. The other is a back-up.

As they say...'just my opinion, your mileage may very....

Keep on pickin'!
